KMP search, substring operations, case conversion, and text analysis compiled from BMB.
Installation
pip install bmb-text
Quick Start
import bmb_text
bmb_text.kmp_search("hello world", "world") # 6
bmb_text.str_replace_all("abcabc", "abc", "X") # "XX"
bmb_text.to_upper("hello") # "HELLO"
bmb_text.trim(" hello ") # "hello"
bmb_text.is_palindrome("racecar") # True
bmb_text.word_count("hello world") # 2
bmb_text.repeat("ab", 3) # "ababab"
bmb_text.hamming_distance("karolin", "kathrin") # 3
